Specification of Letters Patent.

Patented lil'ar. 231, 1929.

Application filed august 31, 1918. Serial No. 252,198.

1 b all "whom it may coaccrn lie it hnovvn that 1., Esme L. CARSON, a citizen. of the United States, residing at llzierlin, in the county of Josephine and State of Uregon, have invented new and useful. improvements in Nut-Locks, ot which the tloilowing is a specification.

This invention relates to improvements in nut locks the object of the invention being to provide an eilicient and inexpensive do vice of this character by means of which a nut may be held against reverse n'ioveinent upon the bolt whether the same is in engagement with the support or not.

With the above and other objects in view, the invention consists in the construction, combination and arrangement 0t devices hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is an elevation, partly in section, of a bolt and nut provided with nut locking means constructed and arranged in accordance with my invention.

Fig. 2 is a detail plan oi the locking Washer showing the same in initial extended position.

Fig. 3 is a detail elevation of the bolt.

In accordance With my invention the bolt 1, Which may otherwise be of any ordinary construction. is provided at the threaded end of a shank with an extension 2 which is flattened on opposite sides as at 3. The nut L is oi usual construction. I also provide a Washer 5 Which is an oblong rectangular strip of metal Which. can be readily bent and Which Will remain in any position in which it may be placed. Near one end oi the Washer is an opening 6 through which the bolt extends. The opposite end of the Washer is provided with a longitiuiinal slot 7 the length of which exceeds the greatest Width of the extension 2 oil? the bolt.

The Washer is placed on the bolt and arranged under the nut -and is then bent in substantially ti form so as to also hear on the upper side or the nut as at 8. The opening 7 receives the flattened extension 9; oi. the bolt, the length of said slot exceed ing the greatest Width o'l' said extension and thereby enabling the Washer to be bent over the nut. By the engagement of the sides 01'' the slot with the sides ot the extension 2 the Washer is prevented from turning on the bolt and the intermediate portion 9 of the washer, which is arranged at one side oi? the nut eii'ectually prevents the nut also from turhinp; on the bolt so that the nut is securely locked.

Having thus described my invention, I claim:

In combination with a bolt and a nut thereon, said bolt having an extension at its threaded end flattened on opposite sides, a substantially tl-shasped Washer comprisinn; parallel legs engaging opposite faces oi the nut and a straight member connecting the parallel legs and engaging one side edge oil? the nut, said Washer having an opening near its inner end through which the bolt passes and having; a longitudinal slot near its outer end through which the flattened extension of the bolt passes the length of said slot eliceedingr the greatest width of the said extension and thereby enabling the washer to be bent over the nut.

In testimony Whereoit' I aiiix my signature.

EARL L. CARSON.
